Title: Changes to the process parameters as a function of the thermal loads of a heat source especially during pulse soldering
Inventor: ZIMMER GERO
IPC: B23K3/03
Filed: 1988-08-23
Abstract: In so-called pulse soldering and similar methods for the thermal treatment of parts, the thermal energy required for melting the solder is mainly transferred to the parts to be joined by the thermal contact, preferably of a soldering tool, produced by the acting force. Here, these soldering tools can in principle be programmed in their behaviour for temperature, time and acting force on the parts. Gases can also be used for additional control. The method according to the invention describes the determination of the extent of the thermal contact by measuring the thermal load in/by these parts in order to gain from this an insight into the time sequence of this joining action. From this, the other process parameters can then be automatically changed according to the invention, and thus the flow of thermal energy and mechanical movement for the thermal treatment or the joining action and further mechanical and thermal behaviour can be influenced.
Patent DE-3830790-A1 (DE)
Inventor: FREUND ECKHARD PROF DR ING
IPC: G05D1/02
Filed: 1988-09-09
Abstract: In critical traffic situations, reactions to danger are frequently too slow and inappropriate because of obstacles. In such cases, collisions can be avoided automatically by an acceleration, braking or swerving manoeuvre. This is achieved by means of a hierarchical process and associated device. Vehicle- and course-related data are recorded by sensors. Ideal course signals are derived from these data and transmitted, together with data concerning an obstacle course recorded for example by sensors, in a second hierarchical step of an anti-collision device. Said device controls the regulating elements of the vehicle control so as to prevent collision in a third hierarchical step. The process and device are particularly suitable for road vehicles.

Patent DE-3940717-A1 (DE)
Inventor: MANSCHWETUS HELMUT
IPC: B23D31/00
Filed: 1989-12-09
Abstract: In blade holding devices sleeves are arranged concentrically about the blade securing screws, in order to relieve the blade securing screws from lateral shearing force components and vertically acting stripping forces resulting, when the blade slide is moved upward, from the friction between the blade and the scrap metal in the feed channel. For the removal of the blade, lateral wearing plates in the feed channel have to be removed. In order to permit the removal of the blade from the holding device without dismantling the wearing plates of the feed channel and, at the same time, retaining the sleeves, a short sleeve is provided, that, in an operational position of said scrap cutter, ascertains form-locking between the blade and the blade slide or the blade support and rests against a long spacing sleeve that is concentrically arranged about a shaft of the blade securing screw and is held by the blade securing nut. The short sleeve is also concentrically arranged about the shaft of the blade securing screw. After removal of the blade securing screws, the short sleeve may be slid toward the backside of the blade, permitting the removal of the blade in a downward direction. A dismantling of the lateral wearing plates is unnecessary.

Patent DE-3942809-A1 (DE)
Inventor: BAYER FRANZ
IPC: E06B3/66
Filed: 1989-12-23
Abstract: To make a space-keeping profile, especially one for thermopane glass, a hollow section (2) is bent in each of the corner regions of the profile, for example with four corresponding bends of about 90 DEG , in order to form a square or rectangular profile. The hollow section (2) is first of all filled with desiccant, during which procedure it can be arranged in a tilted position. At its lower end, it is sealed, for example, with a straight connecting piece (9), by means of which it is connected to a further hollow section (2) or, if the length of the hollow section (2) corresponds exactly to the profile circumference itself, it can be sealed. The desiccant (3) is introduced into this hollow section (2) at the upper end (12), after which it is laid in an approximately horizontal position and fed to a bending device and finally bent to form the profile. According to the invention, the hollow section is filled completely, although, if required, it may also be filled only partially, and then partially emptied again to give a reduced degree of filling, and the partial filling which it contains is distributed over its length with the hollow section (2) in a horizontal position and the hollow section is then bent. The partial emptying and/or the distribution of the partial quantity of desiccant contained in the hollow section - in particular after partial emptying has taken place - can be distributed with the aid of a vibrator (10). The vibrator (10) can shake the hollow section (2) backwards and forwards with the desiccant quantity contained in it in an approximately horizontal direction in the direction of alignment of the hollow section. The partial quantity of desiccant discharged can be measured using an appropriate measuring device in order thereby to determine the partial quantity remaining in the hollow section and, after partial emptying, to switch over the vibration process automatically to a mode which gives the most uniform distribution of the remaining desiccant in the hollow section (2).

Abstract: A process and electronic ballast allow the brightness (dimming) of gas-discharge lamps (GE) to be controlled, especially in the case of gas-discharge lamps of a different type, such as argon or krypton lamps, and gas-discharge lamps of different rated power (PN). In this case, an invertor (20) is provided which emits an AC output voltage (uw) of variable frequency (f) and/or of variable duty cycle (d) to a load circuit (10) containing a gas-discharge lamp (GE). Furthermore, a first and a second current measuring element (25, 26) are provided for detecting a lamp current (IWrms, Ilamp) and a DC current (Idc) taken by the invertor (20) or intermediate-circuit smoothing capacitor (C0), and a first voltage measuring element (27) for detecting intermediate-circuit DC voltage (U0, Udc) for the invertor (20). The circuit arrangement and the specified process are intended to achieve an improved brightness control, particularly in a small brightness range. In addition, it is intended to achieve independence from the lamp type. To this end, the current measurement variables (IWrms, Idc) are combined in a synthetic current measurement variable (Iq), and the synthetic measurement variable (Iq) thus formed is multiplied by, or quasi-multiplied by, the DC voltage measurement variable (Udc), as a result of which an actual power variable (Pmess) which essentially represents the absorbed or emitted lamp power (Pout, Pin) can be formed for a power control loop (40, 20, p, Pdes, GE, 10). <IMAGE>
